Systems, methods and devices for use in tracking are described, using optical modalities to detect spatial attributes or natural features of objects, such as, tools and patient anatomy. Spatial attributes or natural features may be known or may be detected by the tracking system. The system, methods and devices can further be used to verify a calibration of a tool either by a computing unit or by a user. Further, the disclosure relates to detection of spatial attributes, including depth information, of the anatomy for purposes of registration or to create a 3D surface profile of the anatomy.

One variation of a method for tracking objects within a surgical space during a surgery includes: based on a first image depicting the surgical space at a first time, detecting a first object and a constellation of objects in the surgical space, estimating distances from each object—in the constellation of objects—to the first object, and calculating a contamination risk of the first object based on contamination scores and distances to the first object for each object in the constellation of objects; calculating a contamination score of the first object based on a combination of the contamination risks of the first object during the surgery; and, in response to the contamination score of the first object exceeding a threshold contamination score prior to contact between the first object and a patient, serving a prompt within the surgical space to address sterility of the first object.

An arthroscopic port introduction system includes an elongate hollow introducing needle and an elongate stylet sized and adapted to be disposed within the elongate hollow introducing needle together forming a single tissue-penetrating tip. The system also includes an elongate hollow enlarging shaft adapted to be disposed over the elongate hollow introducing needle. An operative tissue-penetrating length of the elongate hollow introducing needle is exposed beyond a distal end of the elongate hollow enlarging shaft. The elongate hollow introducing needle can be removed in a proximal direction from the elongate hollow enlarging shaft. An arthroscopic port sheath is disposed over the elongate hollow enlarging shaft and an operative tissue-penetrating length of the elongate hollow enlarging shaft is exposed beyond a distal end of the arthroscopic port sheath. The elongate hollow enlarging shaft can be removed in a proximal direction from the arthroscopic port sheath.

A surgical light is provided, the surgical light comprising a light head including at least one illuminant configured to generate an illuminated area on a surgical site, and a sensor attached to the light head, wherein the sensor is configured to identify items used in surgery, and the sensor is attached to the light head such that a detection volume of the sensor is directed to the illuminated area.

A device sized and shaped for insertion into a body comprising: at least one mechanical limb comprising: a support segment; a first flexible section extending from the support segment and terminating in a coupling section; and a second flexible section extending from the coupling section and terminating in a tool or a connector for a tool; wherein a long axis of one or more of the flexible sections is bendable in a single bending plane; wherein a long axis length of the first flexible section is at least double a maximum extent of the first flexible section perpendicular to a flexible section long axis; wherein a long axis length of the second flexible section is at least double a maximum extent of the second flexible section perpendicular to a flexible section long axis.

Methods and devices are disclosed for puncturing tissue, comprising a puncture device for puncturing tissue and a supporting member for supporting the puncture device. The puncture device is capable of being insertable within the supporting member and being selectively usable in co-operation therewith during a portion of a procedure for puncturing tissue and wherein the puncture device is usable independently therefrom during another portion of the procedure. The puncture device comprises visual or tactile markers for determining the relative positioning between puncture device and supporting member.

A system for testing sutures includes a test bench having a rotatable table, a framework supporting the test bench and the rotatable table above a surface, and a continuous passive motion (CPM) machine mounted on the rotatable table. The CPM machine is configured to rotate between a first position in which the CPM machine is upright and located above the rotatable table and a second position in which the CPM machine is inverted and located below the rotatable table. The system includes a fluid supply subsystem for directing an infusion fluid toward the CPM machine, a pump for circulating the infusion fluid in the fluid supply subsystem, a heat exchanger for heating the infusion fluid, a fluid collection tray located below the CPM machine and the rotatable table, and a pressure monitoring subsystem for monitoring a pressure level of the infusion fluid.

A sterile container for sterilizable medical goods includes a receiving space for the medical goods and a data acquisition unit for acquiring parameter data of influencing variables that act on the sterile container. The sterile container includes an NFC module with at least one sensor for acquiring sterility-relevant and/or sterilization-relevant data and a data logger for recording and storing data from the sensor at a recording interval. The sterile container can be monitored by a method that is automatic and sterile-container-specific.

Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible sizing member having a distal end portion arranged for anchoring in the patient's stomach and for enabling fluids to be removed from the patient's stomach. The elongated flexible sizing member is configured to produce near infrared fluorescence to facilitate its location within the patient's stomach and to provide visual information about location of certain relevant internal anatomical features. Suction is applied to the patient's stomach by the distal end portion of the instrument to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the instrument to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

An instrument for establishing orientation of a pelvic prosthesis comprises a hub, a first arm attached to and extending from the hub, and a second arm attached to and extending from the hub. The first and second arms define a nominal plane of the apparatus, and may extend from the hub at an angle relative to each other. Distances between the first and second legs and between the first and third legs are adjustable. The first, second, and third legs have tips, and the tips of the first, second, and third legs define a plane having a predefined geometric relationship to the nominal plane of the apparatus.
